It is shown that balancing A, D, E-vitamin nutrition in high-producing cows of black-and-white breed by synthetic A, D, E-vitamin preparations up to 135 % of the standard in force allows to more fully realize their genetic potential and obtain higher milk productivity (3.8 %), milk fat (4.5 %), milk protein (7.4 %), and to increase biological full value of milk (for A, E-vitamin activity and criteria of its estimation for producing lactic-acid products and cheese making), as well as to normalize the content of somatic cells up to the standard and to reduce the fraction of nitrate nitrogen (by 36.5 %)
